If the foregoing discussions do not resolve the disagreement in a reasonable time (which will not exceed [ * ]), a representative sample of such Product and/or relevant documentation will be submitted to an independent testing laboratory (in the case of an alleged failure to meet Specifications) and/or independent cGMP consultant (in the case of an alleged failure to comply with cGMP), as appropriate, that are, in each case, mutually agreed upon by the parties for tests and final determination of whether such Product conforms with such Specifications and/or cGMP (if applicable). The laboratory must meet cGMP (if applicable). The laboratory and consultant, as applicable, must be of recognized standing in the industry, and consent to the appointment of such laboratory and consultant will not be unreasonably withheld or delayed by either party.

NOW, THEREFORE, the Parties desire, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, to amend the Services Agreement as set forth in this Second Amendment.

Article 1
DEFINITIONS

During this review period, the parties agree to respond promptly, but in any

event within [ * ], to any reasonable inquiry or request for a correction or change by the other party with respect to such Batch Documentation.

2.9Amendment of Section 6.5. Section 6.5 (Disputes) of the Services Agreement is hereby retitled as “Non-Conforming Product; Disputes” and is amended in its entirety as follows:

6.5Non-Conforming Product; Disputes.

(a)Upon Atara’s receipt and review of the Batch Documentation within the time period set forth in Section 6.3, Atara shall in accordance with Section 6.3 notify Manufacturer in writing if Atara believes, in good faith and based on reasonable grounds that any Batch (i) fails to conform to the Specifications, (ii) was not Manufactured in compliance with cGMP (if applicable) or (iii) was not Manufactured in compliance with the Manufacturing Process (as modified by any Planned Deviations, if any, that were preapproved in writing by Atara) (such Batch, a “Non-Conforming Batch”). Non-Conforming Batches shall be addressed in accordance with the remainder of this Section 6.5 and Section 6.6.

(b) If a Batch is a Non-Conforming Batch, then a root cause analysis on such Non-Conforming Batch will be undertaken in accordance with subsection (c) below (the “Investigational Process”). Atara will be required to pay for [ * ] of the amount set forth in invoices for Product that is a Non-Conforming Batch within the time frame required under the applicable Work Order, with the remainder of such invoiced amount held pending the determination of an Investigational Process. Payment of an invoice by Atara will not constitute a waiver of remedies available to Atara under Section 6.6, except for claims that a Batch is or was a Non-Conforming Batch where Product in such Batch is or was approved for Final Disposition (as defined in Exhibit E).

(c)Without limiting subsection (b) above, the parties agree that any Non-Conforming Batch (or where the parties cannot agree, any Batch that either party believes to be Non-Conforming) will first be reviewed through the Investigational Process by a joint “Investigation Team” made up of [ * ]. If the Investigation Team is unable to make a determination of the root cause within [ * ] following identification of the Non-Conforming Batch (or submission of a disputed Batch to the Investigational Process for determination of whether it is Non-Conforming), an analysis and review will be performed by the joint “Materials Review Board.” The Materials Review Board shall [ * ].

MISCELLANEOUS

3.1No Waiver. Nothing in this Second Amendment is intended to operate as a waiver of any claims either Party may have against the other Party arising prior to the date of this Second Amendment with respect to the performance of the Services or otherwise under the Services Agreement, provided that Atara shall have no right to make a claim for refund or replacement under Section 6.6 (as amended by this Second Amendment) on the basis of Non-Conformance in connection with any Batch approved by Atara for disposition or final disposition prior to the date hereof, and all of such claims are waived and extinguished upon execution of this Second Amendment.
